Abstract: First multicolour photoelectric light curves of the eclipsing binaries AQ Tuc and AY Vel obtained in 1965 and 1969 at the Leiden Southern Station using Walraven VBLU filters were analyzed by the Wilson-Devinney's code. Our analysis confirmed the contact configuration for AQ Tuc and revealed that AY Vel is an almost contact system with q approx. 3. The absolute radii of the components of AQ Tuc derived from the combination of our photometric and available spectroscopic elements are R_1 = 2.03 +/- 0.11 R_Sun and R_2 = 1.30 +/- 0.07 R_Sun.
